EIP Designer: Bridging the Gap Between EA and Development

This article presents the EIP Designer project, an Eclipse-based tool for introducing integration patterns into an EA design, providing fluidity and continuity while filling the gap existing between EA practices and concrete software development.

The demand for IT project managers is increasing. Agile methodologies support collaboration with distributed teams for creative problem solving. The Internet of Things, cloud, big data, and cyber security will continue to dominate the IT landscape. Project managers have to pioneer IOT initiatives, be prepared for the influx of data and ensure that deliverables from their projects are secure.

The discussion on ITIL vs. DevOps is a common one. There are different views: ITIL and DevOps have different mindsets; ITIL and DevOps are compatible; they are different but both have their place in the IT department. Charles Betz, member of the Open Group IT4IT Forum, argues that their principles are at odds. ITIL is trapped in a phased workflow mindset. DevOps embraces lean product management.

An interview with Rob Howe, host of the MDSE session at the software engineering conference and CEO of Verum, about the state of practice and recent developments in model driven software engineering, the usage of this technology, whether he considers model driven software engineering to be a proven mature technology, and what the future will bring us in model driven software engineering.

When developing large complex systems and dealing with legacy code, organizations need to have systems in place to support integration and delivery. Modularization can help when agile is scaled with multiple teams that are working in parallel. It's not the framework or method that will do the job, but how your people will make it work to solve your problems says Hans Dekkers.

InfoQ interviewed Frank Penning, PMO manager from Philips Lighting, about the main challenges that Philips Lighting is facing in product development, why Scrum is not enough, how they apply SAFe, and the benefits that they have gained from deploying agile methods for product development.

On June 12, 2015, the Jetty Project released version 9.3 of their flagship open source embedded application server, that day being the 20th anniversary of the project's beginning. Features of the release include HTTP/2 server (and client) support, Java 8 as a minimum, more Java NIO integration and an overhauled scheduler. They also removed SPDY networking support and fixed over 400 bugs.

Last week, RedHat hosted a "Microservices Architecture Developer Day" in London, and presented a set of technologies and patterns that can be used to create microservice-based applications using open-source solutions like Kubernetes, Docker, Fabric8 and Maven. Read on for more details about the day, including links to the presentations and demo videos.

Oracle is considering including JEP 248, making G1 the default garbage collector on server configurations, into the list of JEPs targeting Java 9. The decision has triggered some debate among the Java community, with many arguing that the CMS collector could have been more suitable.

There is tremendous value in microservices, probably giving us the best environment we have ever had for doing Domain-Driven Design (DDD), Eric Evans stated in his keynote at this year’s DDD Exchange conference in London. Iteration is the most important key to good design and microservices is the second attempt, after SOA, to get things right.

Apache Parquet, the open-source columnar storage format for Hadoop, recently graduated from the Apache Software Foundation Incubator and became a top-level project. Initially created by Cloudera and Twitter in 2012 to speed up analytical processing, Parquet is now openly available for Apache Spark, Apache Hive, Apache Pig, Impala, native MapReduce, and other key components of the Hadoop ecosystem.

InfoQ interviewed Andrea Provaglio about business models for execution, optimization and discovery, dealing with uncertainty and leveraging it to create business value, understanding both value and cost, growing a discovery mindset, and creating a culture where people have the courage to make mistakes and can learn from them.

During the last months Martin Fowler among others have claimed that a microservices architecture should always start with a monolith, but Stefan Tilkov is convinced this is wrong, building a well-structured monolith with cleanly separated modules that later may be pulled apart into microservices is extremely hard, if not impossible in most cases.

Astrid Atkinson, director at Google, drew on their experiences over the last decade to present some rules and advice on engineering for the long term. The Velocity Conference 2015 attendees at Santa Clara learned that it's crucial to imagine that you're going to be wildly successful, that complexity mustn't be eliminated but managed and that the focus should be on scaling systems not teams.
